The box-office odds are ever in the favor of Chris and Liam Hemsworth. With Marvel's "The Avengers" claiming a record-breaking $200 million in its first three days and "The Hunger Games" bowing at just over $150 million, the Australian brothers have assembled the top two opening weekends of 2012. Talk about the thunder from Down Under!

Six weeks after its debut, "The Hunger Games" continues to perform well, raking in a total gross of more than $380 million. And though it will undoubtedly fall in its second weekend, the box-office experts who spoke to MTV News were bullish about the continued heroics of "The Avengers."

"I project it will become the fastest film in history to smash the $1 billion global box-office mark, doing it in about 20 days or so," Box Office Guru editor Gitesh Pandya said. " 'Avengers' just might end up becoming the highest-grossing non-James Cameron film ever."

Interestingly enough, 2012 marks the first time in which the Hemsworth brothers have had competing films at the cineplex. Chris broke onto the scene with a small part as Captain Kirk's father in 2009's "Star Trek," though his most high-profile role to date is arguably as the titular, hammer-heavy Norse god of 2011's "Thor." Brother Liam's entry into American cinema came courtesy of Nicholas Sparks' 2010 romance "The Last Song," in which he played the beau of real-life girlfriend Miley Cyrus.

And there will be plenty more Hemsworth to come in 2012. Next month, Chris will continue his weapon-wielding ways in "Snow White and the Huntsman," co-starring Charlize Theron and Kristen Stewart. In November, he'll star alongside his brother's "Hunger Games" cohort Josh Hutcherson in the action flick "Red Dawn." Liam also has a pair of films readied for this year: "AWOL," a war-time drama co-starring Teresa Palmer, and "The Expendables 2," in which he'll go toe-to-toe with action vets Bruce Willis, Arnold Schwarzenegger, Sylvester Stallone and Chuck Norris (just to name a few).
